Citect SCADA trending problem

Hi guys,

I have a Modicon Momentum PLC communicating with a Citect SCADA.

The problem is, the trend in citect is not match with the calculation in Momentum PLC. I had verified this after I go online with the Momentum and Citect.

I used a sub_real block of Momentum. The output of the block which is also accessed by citect is fine and accurate, however, the two inputs( IN1 and IN2)which are also accessed by citect are not. I also adjusted the trend sampling of the citect, sadly, it has an error.

Does anyone had this same problem before? Is there any adjustment that I need to do?

Thank you.

Somebody will be able to help, firstly, what version of Citect, and what is the error that you are seeing ?

You may have to scale the tag in Citect.
